-// Testing class that allows embedders to inject an arbitrary CldDataHarness
-// implementation into the runtime by defining a subclass of

-// returned by Get() to obtain CldDataHarness instances.

-// There is significant nuance to obtaining a CldDataHarness object at runtime.
-// For each of the "stock" CldDataSource implementations ("standalone",
-// "static" and "component"), a CldDataHarness implementation is available and
-// the default implementation of the CldDataHarnessFactory class knows how to
-// do the right thing; but embedders can provider entirely custom CldDataSource
-// implementations, and browser tests need to be able to use those data sources
-// correctly at test time. Embedders implement a subclass of
-// CldDataHarnessFactory and set it using Set(), below, to enable browser tests
-// to function as realistically as possible with the embedder's data source.
